Patent JP-S6449321-A (JP)
Title: Digital dll circuit
Inventor: OYAMA KOYO
IPC: H03L7/06
Filed: 1987-08-19
Abstract: PURPOSE:To secure the duty in an ultra high frequency area, and to suppress the influence by a periodic fluctuation and an element characteristic fluctuation, by measuring an input by a timepiece based on a buffer gate delay time as a reference, and generating a J layer clock from its result. CONSTITUTION:A latching circuit 16 receives delay period clock signals C1-Cm from a delay circuit 14, by its input terminal 20, and receives a negative phase reference double period clock signal C from a flip-flop 11 by its terminal 21 and latches the delay double period clock signals C1-Cm, and outputs opposite polarity latch outputs (Q1-Qm) to a priority encoder 22 of the next stage. This encoder 22 determines the lowest number K (E1-El) from among the latch outputs (Q1-Qm) and inputs it to a J equally divided number generating part 23 of the next stage. This J equally divided number generating part 23 selects a number N1 of a first divided point at the time of J equal division, with respect to the lowest number K which has been inputted, and outputs numbers of J-1 pieces of divided points to a terminal 25 of a signal selecting part 24.

Title: Stepping motor apparatus
Inventor: MIYAZAKI KUNIO
IPC: B41J19/30
Filed: 1988-08-17
Abstract: PURPOSE:To suppress the vibration generated by a moving member to a low degree by changing acceleration/deceleration patterns according to the stop position of the moving member. CONSTITUTION:A CPU 6 selects one of acceleration/deceleration patterns corresponding to the targeted stop position of a carriage to successively load data and outputs a motor driving control pulse signal to a drive circuit 8 through I/O 9 at the time interval corresponding to said data. The drive circuit 8 changes over the exciting phase of a carriage motor each time it receives a motor driving control pulse to apply voltage. By changing the acceleration/ deceleration patterns corresponding to the difference of the targeted stop position of the carriage, more proper acceleration/deceleration can be performed and, therefore, the accuracy of the stop position of the carriage can be enhanced and printing quality can be enhanced.

Title: Water paint composition applycable to oil-deposited surface
Inventor: TAHIRA NOBUHIRO
IPC: C09D5/00
Filed: 1983-10-31
Abstract: PURPOSE:To provide the titled compsn. having extremely good adhesion to oil- deposited metallic surfaces, by incorporating a specified quantity of a specified surfactant. CONSTITUTION:The titled compsn. contains 0.1-10pts.wt. surfactant having an HLB value of 8-18 per 100pts.wt. water paint compsn. consisting of a resin, a pigment, a solvent, etc. When the surfactant has an HLB value less than 8, oil is poorly emulsified and dispersed, while when the HLB value exceeds 18, it can be adsorbed by oil, but dispersion in water is poor. Hence, an HLB value in the range of 11-15 is particularly preferred. Preferred resins include those having a polar group such as an epoxy, urethane, or carboxyl group, because these polar groups have affinity with the surfaces of metallic sheets. As compared with conventional soapless water paints, the initial adhesion of the paint to metal is high and the paint has very good adherability to oil-deposited surfaces.

Abstract: PURPOSE:To form resist patterns, each having roughly vertical sidewalls, by a method wherein a P-type resist is applied to on the surface of a matter to be processed and after a pattern exposure finished, the surface of the resist is exposed to a plasma-containing atmosphere and thereafter, a developing is performed. CONSTITUTION:A novolak resin P-type resist 2 is applied to the whole surface of an Si substrate 1 by a spin-on coating method and is formed in a film thickness of 1.0mum or thereabouts. After that, a prebaking is performed to volatilize the organic solvent in the film 2. A pattern exposure is performed on a desired part alone of the film 2 with a KrF excimer laser beam 3 of a wavelength of 248nm. When the whole substrate 1 which ended an exposure is exposed to a CF4 gas plasma-containing atmosphere 4 for about one minute, the surface of the film 2 is cured by the radical reaction of the CF4 gas and the resistance to a developing solution of the cured part is increased. A developing is performed to remove parts, which are irradiated with light, of the film 2 and lastly, a baking is performed to obtain patterns of a desired form.

Title: Thin-film transistor and liquid crystal display device
Inventor: FUKUDA KAICHI
IPC: G02F1/1368
Filed: 1993-08-19
Abstract: PURPOSE:To eliminate the influence due to external electric field by a highly resistant semiconductor film so as to reduce the influence on the bending of an energy band of a channel semiconductor layer by adopting the highly resistant semiconductor having a specific band gap for a protective film which is to be arranged on the upper side of the channel semiconductor layer. CONSTITUTION:A protective film 10 is formed on a thin-film transistor part, a source electrode 8 and a drain electrode 9. Then a highly resistant semiconductor film 10b whose optical band gap 1.9-3.0eV is formed on the film 10. Thus, the influence due to external electric field can be eliminated by the highly resistant semiconductor film, so that it is possible to reduce its influence on the bending of the energy band of a channel semiconductor layer. Since the highly resistant semiconductor film has a high resistance property, no direct leakage through the protective film is generated in stable OFF-state property of the thin-film transistor. On the other hand, current control by using gate electrode electric field is performed against the channel semiconductor layer, thereby hardly reducing the ON-state current.

IPC: G21C15/243
Filed: 1990-08-03
Abstract: PURPOSE:To reduce the extent of flow exciting force acting on a control rod driving housing as well as to make improvements in reliability by setting up a downward guide plate in the opening of a shroud support leg supporting an internal pump. CONSTITUTION:A flow from a leg opening 7b between pumps themselves is fully mixed with a colliding flow from adjacent pumps 2, so that it has a plat velocity distribution in the vertical direction. Accordingly, a bending stress due to flow exciting force acting on a control rod driving housing 5 becomes large enough. At this time, with a downward guide plate 9 set up in an upper end of the leg opening 7b between these pumps, the flow with the flat velocity distribution in the vertical direction at the opening 7b comes a downward flow along the bottom surface of a pressure vessel 1 owing to this plate 9. With this constitution, the flow exciting force acting on the control rod driving housing 5 is thus reduced.

Filed: 1989-08-08
Abstract: PURPOSE:To prevent the degradation in display grade by the electrification of spacers by setting the specific resistance on the surfaces of the spherical spacers between a pair of substrates at about the same level as the specific resistance of a liquid crystal. CONSTITUTION:The spacers 6 are formed by mixing carbon of about 0.01mum grain size at the time of reaction of the suspension polymn. of the crosslinked polymer of divinyl benzene. The specific resistance of the spacers is about 10<10>OMEGAcm with respect to 2X10<10>OMEGAcm specific resistance of the liquid crystal. The specific resistance of at least the surface thereof may be about the same level as the specific resistance of the liquid crystal. The transparent substrates 2a, 2b are sealed by a sealing member 5 and the liquid crystal 7 is packed therebetween. The specific resistance of at least the surface of the spacers is about the same level as the specific resistance of the liquid crystal and, therefore, static electricity generated at the time of applying a driving voltage to this liquid crystal display device disperses uniformly without being electrified on the spacers alone and is discharged through the electrodes. The drop of the threshold voltage by the liquid crystal around the spacers is, therefore, prevented and the degradation in the display grade is prevented.
